I really find it useful for finding weeds off of the weedline. I was amazed at how much weed growth is out there away from the major beds of weeds. It’s not easy, or sometimes impossible to see the fish in weeds. We are so used to seeing the pro’s out on a smooth reservoir but when your boat is moving it’s hard to tell a fish from a weed. Not to mention, you are moving east, the wind is from the south and you have to angle the trolling motor away from the weeds to steer. Hard to cast to the fish that way.
Plus, here in MN, we have so many fish cruising around it’s hard to tell what you have in front of you unless it’s big like a musky. But it is great for scanning for stuff like weeds, rocks and baitfish. You will most likely catch more fish with it than without. Also, keep in mind, the cone angle is pretty narrow so you have to cast straight along the cone or you don’t see your lure. Not easy in a wind or a very long cast.
